The General Atomics Avenger (formerly Predator C) is a developmental unmanned combat air vehicle built by General Atomics Aeronautical Systems for the U.S. military. Its first flight occurred on 4 April 2009.[4][5] Unlike the previous MQ-1 Predator and MQ-9 Reaper (Predator B) drones, the Avenger is powered by a turbofan engine, and its design includes stealth features such as internal weapons storage, and an S-shaped exhaust for reduced infrared and radar signatures.[6] The Avenger will support the same weapons as the MQ-9, and carry the Lynx synthetic aperture radar and a version of the F-35 Lightning II's electro-optical targeting system (EOTS), called the Advanced Low-observable Embedded Reconnaissance Targeting (ALERT) system.[7][8] The Avenger will use the same ground support infrastructure as the MQ-1 and MQ-9, including the ground control station and existing communications networks.[4]

Operational history[edit]

Flight testing[edit]

The first flight of the first prototype Avenger occurred on 4 April 2009 at the company's Grey Butte Field Airport Flight Operations Facility in Palmdale, California. The aircraft took off and landed without any discrepancies and was ready to fly again once refueled. Following flights were performed successfully on 13 and 14 April.[9] The second prototype Avenger performed its first flight on 12 January 2012, meeting all performance objectives and refining the first prototype design to an operational capability. The Tail 2 prototype featured a four-foot longer fuselage to accommodate larger payloads and more fuel. This larger Avenger can carry a larger payload of up to 3,500 pounds (1,600 kg) of weapons internally and on its wing hard points.

On 15 February 2012, the Air Force cancelled its MQ-X program, which was supposed to find an aircraft to replace the MQ-9 Reaper.[10] The Sea Avenger variant is part of the Navy's Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) program. If it is selected by the Navy, the Air Force may consider buying the ground-based version for service.[11]

On 15 November 2012, the Avenger flew for three hours while being controlled by the General Atomics Advanced Cockpit Ground Control Station (GCS). The Advanced Cockpit GCS has a wrap-around visual display and multi-dimensional moving map to increase situational awareness and reduce pilot workload. The Advanced Cockpit GCS has flown an MQ-1 Predator and is planned to fly an MQ-9 Reaper as part of an Air Force initiative to enable interoperability with all USAF Remote Piloted Aircraft (RPA).[12]

In July 2013, a third Avenger was scheduled to begin flight testing. Assembly of the fourth Avenger was expected to be finished by spring 2014.[13]

On 27 October 2016, General Atomics flew an extended-range Avenger featuring wings extended by 3.2 m (10 ft) to 23.2 m (76 ft). The extended wings add about 1,000 kg (2,200 lb) of fuel totaling 4,600 kg (10,100 lb), extending endurance from 15 hours to 20 hours but reducing internal payload to 3,000 lb (1,400 kg). Since its first flight in 2009, the Avenger has completed more than 13,000 flight hours, reaching 11,000 hours in July 2016 and accumulating most of those hours within the past three years.[14][15]

Potential deployments[edit]

In December 2011, it was reported that the Air Force had ordered an Avenger and that it would be deployed to Afghanistan. "This aircraft will be used as a test asset and will provide a significantly increased weapons and sensors payload capacity on an aircraft that will be able to fly to targets much more rapidly than the MQ-9 [Reaper] UAS," the USAF said in an announcement. "Since it has an internal weapons bay and four hardpoints on each wing it will also allow greater flexibility and will accommodate a large selection of next generation sensor and weapons payloads." The aircraft ordered was the original Tail 1 prototype version. This announcement sparked rumors that the aircraft would be deployed to monitor neighboring Iran and Pakistan. These allegations were made because the Avenger is stealthy, while the battlespace over Afghanistan is free of radar guided missiles, as well as any other anti-aircraft weapons. The announcement also came two weeks after the Iran-US RQ-170 incident. The Air Force responded by clarifying that the purchase was initiated in July of that year, well before the incident.[16][17] However, the Air Force later clarified that the Avenger was being purchased only as a test asset, and that it was not being sent to Afghanistan. Discrepancies in the solicitation are believed to have caused the misinterpretation.[18] After testing, the Air Force decided that the Avenger version they evaluated offered only modest improvements over the MQ-9 in terms of speed, payload, and reduced signature, and didn't meet survivability and reliability requirements to survive in contested environments needed to warrant buying a new aircraft of the type.[19]

With the drawdown of the War in Afghanistan, the U.S. may lose airbases inside the country that are necessary for striking targets in neighboring Pakistan. Plans are being made to relocate drone bases to other countries in Central Asia to avoid needing U.S. military personnel to protect their bases in Afghanistan. Due to the longer distances from potential targets, General Atomics has pitched the Avenger to the Central Intelligence Agency as a better drone for the mission. The jet-powered Avenger can fly 1,800 mi (2,900 km) from its operating base and stay airborne for 18 hours.[20]

On 26 October 2016, the General Atomics vice president revealed that the Avenger was used to conduct a leaflet drop in Syria.[15]

Export[edit]

General Atomics has offered the Predator C Avenger to Canada as a contender for its Joint Unmanned Surveillance and Target Acquisition System (JUSTAS) armed UAV project.[21] In 2016, the JUSTAS project was prioritized by the Royal Canadian Air Force and Liberal government. The RCAF has requested that the drones be armed, therefore making the General Atomics Avenger the only suitable contender as Northrop Grumman's RQ-4 'Arctic Hawk' is unarmed.[22]

On 22 September 2015, the U.S. stated they backed India's membership in the Missile Technology Control Regime, which would enable them to buy armed drones. Two days later, the Indian Air Force sent a letter to General Atomics saying it wanted to purchase the Avenger.[23]

As of 17 August 2017, General Atomics Aeronautical Systems (GA-ASI) is in the early stages of negotiating the potential sale of as many as 90 Predator C Avenger remotely piloted aircraft to an unidentified international customer. The renewed international interest is believed to be led by India, which has requested access to the capability as a potential follow-on to the planned acquisition of as many as 22 GA-ASI MQ-9B Sea Guardian UAVs[24] and which wanted to acquire 100 Avengers for its air force.[25]

Variants[edit]

Stingray[edit]

On 3 May 2010, GA-ASI introduced Sea Avenger, a carrier-based derivative of the Predator C Avenger UAS, intended to fulfill the U.S. Navy's need for an Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS). The Sea Avenger included a retractable electro-optical/infrared sensor, internal weapons bay, and folding wings. The aircraft's structure was designed with the flexibility to accommodate carrier suitable landing gear, tailhook, drag devices, and other provisions for carrier operations.[26]

In April 2014, General Atomics displayed images of the Sea Avenger at the Navy League Sea Air and Space exposition. As requirements for the UCLASS program were altered from a high-end strike aircraft to an ISR machine operating in permissive environments, the Sea Avenger was modified accordingly. It appeared to have four external hardpoints and a small weapons bay, a wing-mounted buddy-refueling store to perform as an aerial tanker, and a larger airframe with a larger engine. If Navy requirements favored a UAV optimized for permissive ISR over broadband stealth, the Sea Avenger would better meet them, as it was originally pitched as having a reduced signature to be "stealthier" than other aircraft. Sea Avenger stealth capabilities seemed to be limited to higher frequencies like C, X, and Ku bands, instead of broadband stealth effective against low-frequency radar bands like VHF and UHF.[27]

In October 2017, General Atomics released images of its submission for the Navy's MQ-25 Stingray, an unmanned aerial tanker that formed out of the UCLASS effort. The aircraft is an Avenger-based wing-body-tail design with a standard D-704 buddy tank refueling system that has an electro-optical ball like the Predator and Reaper, landing gear that pulls into the fuselage, and a system for maneuvering around the flight deck using gestures from the flight crew. Though specifics are not known, the basic requirements will have the Stingray deliver about 15,000 lb (6,800 kg) of fuel 500 nautical miles (580 mi; 930 km) from the aircraft carrier to increase the F/A-18 Super Hornet's combat radius from 450 to 700 nmi (520 to 810 mi; 830 to 1,300 km).[28] GA-ASI's design is larger than the Sea Avenger and is powered by the Pratt & Whitney PW815 high-bypass turbofan, the same engine used on the Gulfstream G600. Generating 16,000 lb (7,300 kg) of thrust, it is four times more powerful than the Predator C's PW545B turbofan,[29][30] and the most powerful engine used by any Stingray competitor.[31] In addition to structural reinforcements and additional systems for carrier operations, the aircraft is fitted with the same landing gear and arresting hook as the Super Hornet and has space available for future growth to perform ISR and strike missions; it would be able to fuel four to six aircraft at a time.[32]

Avenger ER[edit]

On 27 October 2016, General Atomics Aeronautical Systems, Inc. (GA-ASI) conducted the maiden flight of the Avenger ER. GA-ASI extended the wingspan of the Avenger ER by 3.2 m (10 ft) to 23.2 m (76 ft), and enlarged its fuel capacity by 1,000 kg (2,200 lb) to 4,600 kg (10,100 lb) compared to previous specifications. The aircraft carries up to 1,360 kg (3,000 lb) in its internal payload bay, 227 kg (500 lb) less than previously described. The modifications extend its endurance from the original 15 hours to 20 hours. The Avenger ER utilizes a modified fuselage design (completed in 2012) extended by four feet (to 13.4 m (44 ft)) to accommodate larger payloads and more fuel. Earlier in 2016, the U.S. Federal Aviation Administration granted GA-ASI an experimental certificate that allows it to fly the Avenger in the National Airspace System.[33][34] From 24–25 January 2018, an Avenger ER set a new endurance record of 23.4 continuous hours, exceeding the 20 hour flight test goal and reflecting a 10-hour improvement over the baseline Predator C Avenger. The Avenger ER also has an increased maximum gross takeoff weight (MGTOW) of 19,500 lb (8,800 kg) using a co-cured composite center wing and heavyweight landing gear as well as a dual redundant, light weight brake control capability using a lightweight Hybrid Linear anti-lock brake system.[35]
